A man who turned himself in Tuesday after he was identified a suspect in the shooting death of a man in Gert Town is also a suspect in another killing, New Orleans police said.

Michael Smith, 20, was being sought in a killing in Gert Town early Sunday when he turned himself in Tuesday.

Police said they believe Smith was also involved in the killing of 21-year-old Warren Pryor in Slidell. Pryor was found dead in a parking lot along Gause Boulevard shortly before 11 p.m. Monday.

"This individual does have ties to Slidell and in New Orleans. We do believe he is a suspect in our homicide, but it's still under investigation," Slidell Police Department Chief Randy Smith said.

Investigators said it appears Pryor had been shot three times in the face. His car was later found burned in New Orleans, police said.

"It was brutal the way it was done. I mean, it was horrible," Pryor's aunt, Sandra Johnson, said. "From what they're telling us, it looks like they were trying to force him to take money out of the ATM machine."

Johnson said Pryor was quiet, conscientious and polite.

"He went to work, came home, saved all his money, played video games, didn't really go anywhere," she said.

Smith said the cases are still under investigation.

"This is eight days in the new year, and we've already had the first homicide here in St. Tammany Parish. We're just fortunate and glad someone we have is in custody," Smith said.
